sql - ORA-06553: PLS-306: 调用“SUBSTR”时参数的数量或类型错误

Question

我在 oracle 中运行以下查询，我面临错误ORA-06553。

select cast(cbdev.cbchr(utl_raw.substr(4500, 5, 26)) AS DECIMAL (14, 2)) as grant_held 
  from bs_transaction 
 where account_coid = 'TS 0014 T8324J3L2V' 
   and txn_id = 21;

当语法似乎正确时，不确定为什么 substr 会引发错误。有人可以帮我解决这个问题。

Answer 1

尝试以下操作：

select cast(cbdev.cbchr(utl_raw.substr('4500', 5, 26)) AS DECIMAL (14, 2)) as grant_held 
  from bs_transaction 
 where account_coid = 'TS 0014 T8324J3L2V' 
   and txn_id = 21;
